“Most of us, most of our days, are subject to time. We follow calendars and clocks like slaves. Great dancers, however, seem to govern time, to find and possess it without haste and even, for moments, to suspend it altogether. The music’s pulse runs on apace; but they pack every measure with important-seeming activity, now and then playing with the beat, here a hairbreadth behind and there a bit ahead of the music, sometimes pausing miraculously amid the pressing momentum of the dance.”
